Search for Neutrinos from GRB 080319B at Super-Kamiokande

TL;DR

This study searched for neutrinos coincident with the exceptionally bright GRB 080319B using Super-Kamiokande but found no significant signals, setting upper limits on neutrino fluence from the event.

Contribution

First to perform a neutrino search for GRB 080319B with Super-Kamiokande, establishing upper limits on neutrino emission from this notable gamma-ray burst.

Findings

No significant neutrino coincidences detected

Established upper limits on neutrino fluence from GRB 080319B

Derived constraints on neutrino emission models for this GRB

Abstract

We perform a search for neutrinos coincident with GRB 080319B, the brightest GRB observed to date, in a +/- 1,000 s window. No statistically significant coincidences were observed and we thereby obtain an upper limit on the fluence of neutrino-induced muons from this source. From this we apply reasonable assumptions to derive a limit on neutrino fluence from the GRB.
